Castle Loch, also known as the Scottish Castle, Lord Callan's Castle, or just Callan Castle, is a Sodor landmark situated in the south of Ffarquhar Road. It was found by Toby in Toby's Discovery. It is home to Lord Callan.
It was first seen in the fifth season and was re-opened in the seventh. It has become a popular tourist attraction and appeared often until the eleventh season. It returned to the series in CGI in the fifteenth season episode, Spencer the Grand and has made several appearances since.
